According to the latest data from the market research firm IDC, Apple’s iPad is currently leading the worldwide declining tablet market. While iPad continues to be the best-selling tablet out there, IDC’s quarterly Tablet Tracker shows that Apple’s market share fell below 25% globally due to low-cost iPad alternative devices from Lenovo, Huawei, and LG.

The data reveals that Apple shipped 10.9 million units in the second quarter of 2015. The numbers were 13.3 million units shipped back in 2014 in the same quarter. So the numbers show that, in a market showing negative growth, Apple’s share dropped nearly 3 points from 27.7% to 24.5%.

After Apple, Samsung continues to be the second largest vendor in the tablet market with 7.6 million units shipped during the second quarter of 2015. Samsung has also seen a decline in its number of units shipped and market share from the second quarter of 2014 to the second quarter of 2015. The number of units shipped by the Korean tech giant slipped by one million tablets during the quarter year-over-year, falling from 8.6 million units to 7.6 million units. The market share of Samsung declined by one point from 18% to 17%.

Lenovo, Huawei and LG Electronics are also among the top five tablet vendors with 2.5 million, 1.6 million and 1.6 million global tablet shipments during the second quarter of 2015 respectively.

The tablet market has almost become stagnant over the past few years in which Apple itself is struggling with its iPad sales declining for six consecutive quarters year-over-year. This declining trend may change in upcoming few months as Apple is widely expected to launch three new iPads for the holidays season including an iPad mini 4, iPad Air 3, and much rumored large-sized iPad Pro targeted at professionals and enterprises.
